Aryna Sabalenka says her mentality is "trophy or nothing" as she maintained her pursuit of a third Australian Open title in four years with a dominant quarter-final victory over teenager Iva Jovic.

World number one Sabalenka overpowered rising American star Jovic 6-3 6-0 and awaits either third seed Coco Gauff or Ukraine's Elina Svitolina in the semi-finals.

The 27-year-old Belarusian, a four-time major singles champion, has made the semi-final stage at 14 of the past 17 majors she has contested.

Meanwhile, in the men's singles, German third seed Alexander Zverev awaits Carlos Alcaraz or Alex de Minaur in the semi-finals after defeating American Learner Tien 6-3 6-7 (5-7) 6-1 7-6 (7-3).
